Diode Dynamics S550 Mustang Rear LED Side Markers
Replace the unlit rear side reflectors on an EU Mustang with full-length LED marker strips. Supplied as a pair, with lens finish selected from the menu.
The SMD LEDs use a constant-current driver, non-polar input and integrated transient-voltage protection. The housings are ultrasonically welded and manufactured in the USA. DOT/SAE compliance is stated for the red-lens version, which does not by itself establish European E approval.
Installation and fitment
Ford Mustang S550 2015–2023. The assemblies replace the factory reflectors, but EU cars require a power connection using the supplied harness. The US installation video assumes existing wiring, so follow the separate EU wiring guide for European cars.
